Patent GB-190319098-A (GB)
Title: Improvements in Reducing Valves.
Inventor: ROTH ALBERT
Filed: 1903-09-04
Granted: 1903-11-19
Abstract: 19,098. Roth, A. Sept. 4. Reducing valves; actuating valves.-Relates to a method of supplying steam at an almost constant low pressure to a steam heating-device &c. A high - pressure steam pipe is connected through the valve v to a chamber m, the chamber being connected to the heating- device. The spindle a of the valve v passes through the chamber, and through a stuffing- box b, and abuts against an arm of an angle-lever d. A hollow body k, with a core g which is a bad conductor of heat, abuts against the other arm of the lever. The body k is connected by a pipe to a valve f, which opens when the pressure of the steam in the chamber m exceeds a definite value, and allows steam to pass through the pipe p to the body k; the body k expands owing to the heat, and so turns the lever d, thus closing or partly closing the valve v, and so reducing the pressure in the chamber. The pressure at which the valve f opens is determined by the tension of a spring coil, which tension can be altered by turning the handle h of a screw-threaded sleeve against which the spring presses. When the pressure in the chamber falls, the valve f closes, and so the body k cools, the consequent contraction allowing the valve v to open and the pressure to increase. The valve f may be controlled by a weight or lever, or may be replaced by a float or diaphragm valve, by a valve which opens when a column of fluid is raised, or by a simple throttling arrangement formed by narrowing the cross-section of the connection pipe. The lever d may be replaced by toothed gearing, or the expansion body k may be directly connected with the spindle, or be integral with it.

Title: Improvements in Combined Dining and Billiard Tables
Inventor: BERRY GEORGE DAVIES
Filed: 1903-10-20
Granted: 1904-10-20
Abstract: 22,609. Berry, G. D. Oct. 20. Billiards. - Relates to a billiard table arranged to carry a dining- table top, and to means for adjusting the height and level of the table. The legs are normally of the length required for a dining-table, a n d are provided with arrangements for raising the table to the required height for billiards. Fixed to the billiard table at several points by a flange or lugs a, and preferably into the base of each leg b, is a cylinder or tube c carrying on its inner face several locking-studs d. Engaging with and sliding into the tube c is a grooved pillar e, the grooves passing over and about the studs d. A spindle f, having a collar g and carrying a smaller spindle m, screws into the upper end of the pillar e. Surrounding the spindle m is a collar i, which may rotate free on the spindle, and the surface of which is provided with cam-grooves and recesses k. Resting in the cam-grooves are internally projecting studs carried by a serrated collar l. A spiral spring may be compressed between the upper end of the tube c and either of the collars i, l. When the table is required for billiards, it is raised to approximately the correct height, the tubes c sliding over the pillars e until the studs d engage the collar l. The collar is then raised, and the internal projections of the collar are brought against the edges of the cam-grooves, the collar i being thereby rotated so that the recesses k are brought under the studs d. The table is then allowed to drop slightly so that the studs engage the recesses. The level is adjusted by turning the spindles f, holes h being provided in the collars g for that purpose. The spindles are locked by nuts f. To lower the table, it is first slightly raised until the projections of the collar l cause a further rotation of the collar i, which removes the recesses k from under the studs and allows the table to be lowered. Holes may also be formed in the base of the pillars e, for turning the latter to adjust the level of the table.

Title: Improvements in Brakes for Wheels.
Inventor: WADE ALBERT ABRAM
Filed: 1903-10-31
Granted: 1904-10-31
Abstract: 23,594. Wade, A. A. Oct. 31. Brakes.-Brakes for cycle and other wheels are constructed with readily-detachable parts. In the form shown in Fig. 4 applied to the front wheel of a bicycle, the pivoted brake lever 21 has a recess 9 over which engages a long hook 10 on a rod pivoted at its lower end to the turnedup part 5 of the spring yoke. The lower hooked ends 4 of the yoke pass through holes in the pivoted arms carrying the brake blocks R, and are bent under the brake blocks so that, when the brake lever is released, the resiliency of the yoke withdraws the brake blocks from contact with the wheel. The arms carrying the brake blocks are pivoted on pins c, Fig. 1, which form part of the clips a, b on the forks T. In modifications, the brake lever may have an eyeleted cupped end 12, Fig. 4<e>, into which engages the enlarged upper extremity of the brake rod, and the brake-block holders may have projecting flanges 7, 8, Fig. 5, which engage in slots Q, Fig. 5<a>, in the pivoted supporting-arms. In the application to the back wheel, a bridge, in one piece or two, is secured to the forks by clamps E, E<1>, Fig. 8, and supports the fulcrum of a pivoted lever D connected to the brake cord F. The lever D has a pin H which forms the pivot connecting together the two parts A, B of a yoke carrying the brake blocks. The brake blocks are withdrawn from contact with the wheels by springs C. The cord F passes over a pulley near the top of the forks and round the handle-bar stem S, Fig. 9, to the pivoted thumb-lever L mounted on the handle-bar. The brake cord may be replaced by ordinary connections, and, when the connections pass under the bottom bracket, they pass over a small wheel mounted thereon.

Title: Improvements in Appliances for Adjusting and Working Iris Diaphragms of Photographic Cameras.
Inventor: WATKINS ALFRED
Filed: 1904-03-22
Granted: 1905-03-16
Abstract: 6974. Watkins, A., and Woodhead, C. G. March 22. Actinometers.-A lens mount is combined with an actinometer scale slide in which one slide E, Fig. 5, operates the iris diaphragm to vary the aperture in a constant geometric ratio for equal rotations of the slide. The latter may be accomplished by shaping the effective edges of the diaphragm leaves, a geometric construction for which is described in the Specification, or by combining an ordinary iris diaphragm with a camshaped disc D, Fig. 4, which actuates a pin k fixed to one of the diaphragm leaves. As a further alternative, curved guide-slots, shaped in a similar manner as the above cam or leaves, may be used to guide the leaves. The two pointers J, J', fixed to the slides showing actinic values and exposures respectively, point to the platespeed P and the diaphragm-aperture D to be used. The same scales may be used for lenses of different focal lengths by providing a separate index or pointer for each set. The order of the scales may be relatively altered, and a single scale may be substituted to serve at once for the actinic values and the plate-speeds.

Title: Improvements in or relating to Explosion Engines.
Inventor: POLLARD EDWARD THOMAS
Filed: 1904-04-29
Granted: 1905-03-23
Abstract: 9838. Pollard, E. T. April 29. Gas and like engines, compound. The engine has two explosion cylinders with an auxiliary or low-pressure cylinder between them, all three driving the same crank shaft, and is a modification of that described in Specification No. 14,594, A.D. 1903. The pistons of the explosion cylinders a at the end of their out-stroke uncover ports d, thus allowing the products of combustion to escape past a non-return valve e to a receiver space f and then to the cylinder g, driving a crank at about 120‹ behind the other cranks. At the commencement of the next return stroke in the cylinders a, the valve e closes and the exhaust valves are opened by cams c<1> on a shaft c<2>. The exhaust valve for the cylinder g is opened by a cam once every revolution. This opening of the exhaust port in the cylinders a relieves the piston of back pressure, silences the exhaust, and allows of a more complete combustion. The admission ports are shown at b and exhaust ports at c. The low-pressure cylinder may be arranged at an angle with the other cylinders, and its piston may drive the same crank as the explosion cylinder, or one in line with it. The cylinders a work on the four-stroke and the cylinder g on the two-stroke cycle.

Title: New or Improved Apparatus for Distributing Electric Currents and Producing Electric Pulsations.
Inventor: THOMSON ARTHUR THOMAS MILNOR
Filed: 1905-02-10
Granted: 1906-02-08
Abstract: 2742. Thomson, A. T. M., and Ellis, G. O. Feb. 10. Signals, electric; indicators or annunciators.- Currents transmitted in a number of successive impulses, as in signalling, are caused to pass through several different lines one or more at a time, by means of a multiple-contact switch. with a rotatable arm actuated by a spring or weight released, coincidently with each impulse of current, by an elect o-magnetic escapement. In addition, one or more of the lines contain automaticallyactuated interrupters by which each impulse is broken up into several. Fig. I shows diagrammatically one arrangement of the system. Each current impulse sent from a battery 15 by means of a key or other transmitting-device effects a to-and-fro movement of an electro-magnetic escapement 1, releasing an arbor 33 of a spring-driven train of wheels, not shown, to which a rotatable brush arm 12 of a multiple-contact switch 2 is so connected as to make one-sixth of a revolution at each release. One of the brushes 14 thus moves from one of the segments 7 to the next, and the following current impulse will pass through the next in order of the lines 16; 22, &c. Interrupters 20, 24, &c., consisting of conducting-barrels with projecting teeth adapted to meet spring contacts connected to the lines 16, 22, &c., are geared to the driving-mechanism to make one complete revolution for each release of the escapement 1. Double or multiple brush arms may be used, distributing each current impulse between several different lines. Fig. III. shows the invention applied in telephony to showing indicator numerals by means of revolving drums 40, 41, 42, each of which is actuated by an electro-magnetic escapement in the corresponding line from the multiple - contact switch. The brush arm 12 is actuated as before by an electro-magnetic escapement 1 and key. Another escapement 51, provided with its own key, in a branch line from the battery actuates an interrupter 52 in the common return of the lines 54, 55, &c., by means of which any chosen number of impulses can be sent through whichever of the escapements 43, 44, 45 is in circuit, and the respective drums set to selected numbers. The last contact segment 10 takes the current to lamps 48 which illuminate the numbers. Other indicating or advertising devices may be similarly actuated. Reference is also made to Specification No. 11,708, A.D. 1895, [Abridgment Class Electric telegraphs &c.].

Title: Improvements in Apparatus for Generating Steam from Hot Slag
Inventor: MITCHELL GEORGE
Filed: 1905-02-10
Granted: 1905-10-05
Abstract: 2795. Mitchell, G. Feb, 10. Steam generation by hot slag.-Consists in improvements upon the apparatus described in Specifications Nos. 20,225 and 26,795, A.D. 1902, in which hot slag is received in the compartments of an horizontal rotary feeder and dropped into the water of a boiler, when it is removed from below through a suitable valve. Fig. 1 shows a vertical section of the present arrangement, and Fig. 2 a section of the feeder at right-angles to the view in Fig. 1. As the compartments 14 of the feeder are successively filled with the slag, the rotation of the feeder causes the slag to fall into the water of the generator 3. The comminuted slag is withdrawn from the chamber 28 from below. The steam produced is carried off by the pipe 4. A portion of the steam enters the jacket 11 of the feeder-casings, while the steam which enters the slag-cavities of the feeder when they are presented to the boiler passes by the pipe 28a to the boiler feedtank. Packing-rings 21<a>, 22<a> are retained in place by steam pressure. The steam is admitted from the hollow spindle 27<a>, upon which the feeder rotates, as openings 29 in the feeder come opposite the openings in the horizontal spindle. The slide 24 is provided for closing the generator to the slag-feeder.
